The Types segmentation classifies the market by underlying technology platforms, primarily polymerase chain reaction (PCR)‑based assays, next‑generation sequencing (NGS), fluorescence in‑situ hybridization (FISH), and microarray panels. PCR‑based tests remain the workhorse for detecting single‑gene mutations and methylation changes due to their low cost, rapid turnaround, and established clinical validation, thus securing the majority of test volumes. NGS offers comprehensive genomic profiling, capturing a broader spectrum of alterations and supporting multiplexed panels; its adoption is accelerating as sequencing costs decline and clinicians demand deeper insight for precision oncology. FISH provides cytogenetic visualization of chromosomal rearrangements, valuable in cases where spatial context is critical, albeit with higher labor intensity. Microarray platforms enable high‑throughput expression profiling, useful for biomarker discovery and risk‑score generation but limited by lower sensitivity for rare variants. This market taxonomy illustrates how each technology contributes distinct value propositions, influencing overall market dynamics through pricing, scalability, and clinical utility.
